Exercise 17

A particular gene in dogs contributes to coat color. The two alleles exhibit incomplete dominance. Dogs with genotype mm have normal pigmentation; genotype Mm leads to "dilute" pigmentation; genotype MM produces an all-white dog. If a breeder mates a normal dog with a white dog, what will be the genotypes and phenotypes of the puppies?
If two Mm dogs are mated, what is the probability that a puppy will be all white?
